CEILING ELECTRIC-LIGHT FIXTURE.

Specification of Letters Patent. Patented Feb. 24, 1920,

Application filed July 2Q, 1917, Serial No. 181,705. Renewed December 1,1919. Serial No. 341,796.

To all whom it may concernk" Be it known that I, SOL GARrUNKnL, acitizen of the United States, and a resident of Utica, in the county ofOneida and State of New York, have invented certain new and usefulImprovements in Ceiling Electric Light Fixtures; and I do hereby declarethat the following is a full, clear, andexact description thereof, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe reference-numerals marked thereon, which form part of thisspecification.

My present invention relates to a ceiling electric light fixture of thedirect lighting type as distinguished from the indirect or semi-indirecttypes in that the rays of light are directed outwardly and downwardlyinstead of upwardly. My invention also relates more particularly to thetype of electric light fixtures where'a shade is placed about theelectric lamp in order to shade the eyes from the intense rays of lightcoming from the strong electric lamps commonly utilized, and generallyto diffuse the light and produce the desired so-called day-light effect.Fixtures embodying my invention are particularly adapted for .use incommercial places such as stores, oflices and public buildings, but maybe alsoused as ceiling lights in dwellings. While the fixture hereindescribed will ordinarily have' a difiusing shade of opalescent or othertranslucent characteristics, the fixture may be provided with a clearshade if desired.

The general purpose of my present invention is to provide a new andimproved form of ceiling electric light fixture of the general typementioned. p

A further purpose is to provide an article of the class described thatis very simple in construction and arrangement whereby the fixtures maybe manufactured at a very reasonable cost and may be quickly assembledand readily placed in position upon the ceiling by men having no specialtraining.

A further purpose is to provide a ceiling electric light fixture whereinthe fixture is of such form and is so placed bodily close to the.ceiling that there is no opportunity for dust or other foreign matter tocollect within the shade or within or upon the reflector or upon theelectric lamp or upon the member which dependsfrom the ceiling tosupport the fixture as a whole. In other words I provide a ceilingfixture of such form that the fixture is entirely inclosed from theoutward periphery of the downward facing shade entirely up to theceiling.

A further purpose is to provide an electric light fixture having acasing closely connected to the periphery of the shade and extendingtherefrom upward to the ceiling and entirely inclosing the fixture in asubstantially dust-proof manner.

Another object of this invention is to provide a fixture of the classdescribed having its parts of such form and cooperation with each otherthat the parts may be readily placed in position in a most convenientmanner whereby the shade, the electric lamp, the electric lamp socketand the reflector may be successively removed without interfering withthe rest of the fixture in order to be cleaned, repaired or replaced asneeded.

A further object of this invention is to provide a fixture of the typeoutlined wherein the whole fixture is conveniently supported from orassembled upon one common supporting member which is adapted to beattached tothe ceiling, said" supporting member being entirely inclosedand concealed when the fixture is assembled.

Further purposes and advantages of my invention will appear from thespecification and claims herein.

Fig. 2 is an inverted plan view of the same or the fixture as seen frombelow.

Fig. 3 is a plan view of the same fixture or the fixture as seen fromabove.

Fig. .4 is a vertical sectional view on line H of Fig. 3 but on anenlarged scale and with the electric lamp socket and mostof thesupporting member shown in side elevation.

Referring to the drawings in a more particular description, it will beseen that there is provided a supporting member 6 of any desired form,whereby said member may be afiixed to the ceiling and form the means of'supporting the rest of the fixture and preferably form a part of theelectrical connection to the lamp. A convenient form' of such supportingmember is that shown inthe drawings wherein the supportlng memher 6 isprovided with an upper screw-r threaded portion 7 adapted to be screwedinto a corresponding screw-threaded aperture 8 in a ceiling box or plate9 sultably' fastened in or to the ceiling 30, Closely below thescrew-threaded portion 7 the supporting member 6 is provided with atransversely extending aperture 10 which connects with a downward yeXtending openngll, nto hich fits preferably with:

screw-threaded engagement the head end -12 of the lower part 13 of thegeneral sup 7 porting member 6. As the two parts of the supportingmember 6 are brought together they engage and hold in position a spderlike frame composed of outwardly extend-- ing arms 141, said framebeing provided with a central aperture through wh1ch projects theupwardly extending head end 12 03": the

lower part 13 of the supporting member 6."

It will be understood of course that these details of construction aresimply a con-'- venient and the preferred way of making the supportingmember and that said details of construction may be modified if desired,the essential part being that ,thesupporting memberbe adapted to bereadily attached to the ceiling, provide support for the rest of thefixture and have its lower part adapted to form part of the electricalconnection of the fixture.

The lower part 13 of the general supporting member 6 is adapted to formpart of the means for supporting the reflector 15 which extends fromsaid portion 13 outwardly and downwardly at the desired angle and to thedesired extent. The member 13 is also a part, of the electricalconnection to the incandescent electric lamp 16 placed within thereflector 15, said member 13 being of such construction as to. receivethereinto either the plug end of an electric socket 17 Y or the plug ofan electric lamp direct if so desired. As shown in the drawings themember 13 has at its lower end an upwardly extending aperture to receivethe plug 18 of tion in the member 13 through the usual central openingin the reflector 15'. Into the electrical socket 17 is placed thedesired incandescent electric lamp 16. If desired,

it is obvious that a multiple socket may be used in place of the singlelamp socket shown in the drawings and thus provision may be madeforseveral electric lamps in a fixture instead of the one shown.

Electricalconnection is made in any wellknown way through the member 13by means of wircsQOand 21 extending down as from the ceiling box 9through the transverse opening, 10 and then down through the centralaperture provided inthe upwardly extending head l2'ofthe part 13, e 1 7Below the electrical lamp 16 is supported the shade 22, which as alreadystated will usually be of opalescent or some special form of translucentmaterial; butfmay. as as the construction of my electric light fixtureis concerned-be of clear or transparent material. The shade 22 maybe ofany desired" shape but; will preferably be of such form and proportionsand so placed relative'to the electric lamp 16 and the reflector 15 asto direct the light outwardly and downwardly instead of upwardly. Fromthe periphery.

of the shade 22 and united thereto by a substantia'lly dust proofjointas at 23. there extends upwardly to the ceiling a casing Qtof anydesired material and form, but entirely incl'osing the rest'of thefixture from the shade 2211p to the ceilin In .tliedrawings I have shownone way of supportnig and connecting the shade 22 and easing 24 togetherand to the fixture, .but it will be understood that these means may bemodified very greatly and still have the resulting construction withinthe spirit of my inven :iionhand within the claims hereinafter set .ort

The means I have shown as provided for V supporting the shade 22andcasing 24 comprises the arms 14 projecting outwardly from the generalsupporting member 6 to the casing 24: and thereto secured as by means ofscrews or otherfasteners 25. The shaderQ-Q is. secured immediately belowand,

suspended from the casing 24' as by means of a ring'25 angularshaped incross-section and having its vertical web 26 secured .to the lowerportion of the casing'24 as. by means of screws 27, while the horizontalweb 28 of said ring extends inwardly below the periphery of theshade-22, thus supporting said shade and holding it securely in positionand also efl'ecting a substantially dust proof joint between said shadeand the casing.

It will now be seen that I have provided a ceil ng le tric light fixturewhich is new I and improved in its general construction and combinationof parts and which is very simple, practical and etficient. It will benoted particularly that the electric light fixture herein described isfree from the trouble common heretofore o'f dust, dirt, in sects andother foreign matter gathering upon the upper side of the shade or uponthe surface of the reflector or upon the means lamp or upon either theupper orv the lower used to support the fixture from the ceiling. Thisadvantage results fromhavingv an en'- circling casing inclose the entirefixture from the periphery ofthe shade right up to the ceiling. This isan advantage both as to cleanliness and appearance and also as to reallighting efficiency of the fixture. It is known that where dust, dirtand other foreign substances gather upon a shade located below anelectric lamp said foreign matter soon becomes aflixed to the surface ofthe shade so that it cannot be readily cleaned off. Even where this dirtor other foreign matter does not become burned on to the shade itgreatly reduces the amount of light assin throu h the shade until saidma ta b terial is removed. On account of the position and arrangement ofmost ceiling electric light fixtures there is so much difliculty incleaning them from gathering dirt that the cleaning process is neglectedor done only very occasionall It will therefore be seen that mydust-proof fixture is a decided advantage over those heretofore commonlyused.

It will be seen also that in my construction all exterior surfaces maybe made to face downward or downward and outward and never upward. Thisarrangement of exterior surfaces affords practically no lodgment fordust and dirt and also renders the surfaces easy of access for cleaning.
